With 3 Umbral Blades, specced into Bladestorm, you are hitting 6 times a second. Frostbite has a 25% chance on hit and lasts 4 seconds, so you effectively have 6 stacks permanently on them. It’s not much, but with Reign of Winter and damage scaling it does enough to help take care of tougher enemies/bosses faster.
6 stacks is not much for keeping up 3 Umbral blades on an enemy(when you could be spamming puncture/other skills) and Reign of winter(which isn’t used here) does almost nothing for umbral blades other than the global cold pen (It has flat bow and spell dmg and icicles proc on Bow hits only).
Umbral blades also converts frostbite chance from shock chance meaning its going to be much more of a pain to get decent bleed->frost for puncture and shock->frost for UB. Would be much better imo to ditch it for another skill like Decoy with maxed cold shred nodes+duration and will boost both puncture + HoA dmg.
